Answer 1

Step-by-step explanation:

Back in mid-January, the current coronavirus outbreak was merely an unusual cluster of pneumonia cases. At least, that is what the tally of 41 confirmed infections in the Chinese city of Wuhan suggested. But then cases started appearing in other countries: first one in Thailand, then one in Japan, then another in Thailand, all among people who had travelled from Wuhan.

There were some flights to these places from Wuhan, but for three cases to have already appeared internationally, there must have been a lot more infections in the city that hadn’t been picked up. When researchers used flight data to estimate how many unreported cases there must have been to generate these patterns, it suggested the total in Wuhan was more likely to be in the thousands than the dozens.

During an outbreak, we rarely see the full picture at first, and this is where mathematics is essential. As well as the question of how many cases there really are, we also need to know how severe the disease really is: if someone is diagnosed with the new coronavirus, what is the chance it will prove fatal?

As of 11 February, there had been 395 cases confirmed outside China and one death (which may be the most accurate picture of the outbreak). At first glance, it seems the chance of death must therefore be 1/395 or 0.3 per cent. However, this calculation makes a crucial error.
